Hibiscus ‘MINSYPIN3’

ABSTRACT

A new and distinct Hibiscus cultivar named ‘MINSYPIN3’ is disclosed, characterized by large, single, pink flowers with a darker eye, up to 12 cm in diameter. Plants are well-branched, upright and vigorous. The new variety is a Hibiscus, normally produced as an outdoor garden or container plant.

Latin name of the genus and species: Hibiscus syriacus.

Variety denomination: ‘MINSYPIN3’.

BACKGROUND OF THE INVENTION

The new Hibiscus cultivar is a product of a planned breeding programconducted by the inventor, Patrick Pineau. The objective of the breedingprogram was to look for a new Hibiscus syriacus cultivars with largeflowers and healthy, vigorous foliage. The cross resulting in this newvariety was made during 2004.

The seed parent is the unpatented, proprietary Hibiscus syriacus‘R3-08’. The pollen parent is the unpatented variety Hibiscus syriacus‘Red Heart’. The new variety was identified and selected as apotentially interesting selection in October 2007. Selection was made ata nursery in La Menitre, France.

Asexual reproduction of the new cultivar ‘MINSYPIN3’ was first performedin January 2008 in La Menitre, France, by grafting. Subsequentpropagation has shown that the unique features of this cultivar arestable and reproduced true to type in 6 successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘MINSYPIN3’ has not been observed under all possibleenvironmental conditions. The phenotype may vary somewhat withvariations in environment such as temperature, day length, and lightintensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘MINSYPIN3’ These characteristics incombination distinguish ‘MINSYPIN3’ as a new and distinct Hibiscuscultivar:

-   -   1. Large pink single flower with a red eye.    -   2. Erect plant form.    -   3. Well branched.    -   4. Vigorous.

PARENT COMPARISON

Plants of the new cultivar ‘MINSYPIN3’ are similar to plants of the seedparent variety in most horticultural characteristics, however, plants ofthe new cultivar ‘MINSYPIN3’ differ in the following;

-   -   1. The new variety has more branches than the seed parent.    -   2. The new variety has a dark eye, the seed parent does not.

Plants of the new cultivar ‘MINSYPIN3’ are similar to plants of thepollen parent variety Hibiscus syriacus, ‘Red Heart’ in mosthorticultural characteristics, however, plants of the new cultivar‘MINSYPIN3’ differ in the following;

-   -   1. ‘Minsypin3’ is more vigorous with more branches than the        pollen parent.    -   2. ‘Minsypin3’ has a pink flower with a dark eye, the pollen        parent has a white flower.    -   3. ‘Minsypin3’ has a larger flower (12 cm) than the pollen        parent (8-10 cm).    -   4. ‘Minsypin3’ has small pink petaloid stamens, the pollen        parent has none.    -   5. ‘Minsypin3’ has got longer red feathering (0.5 to 1 cm) which        is absent in the pollen parent.    -   6. ‘Minsypin3’ has shorter pubescence on its seed than the        pollen parent.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘MINSYPIN3’ can be compared to the varietyHibiscus syriacus unpatented. These varieties are similar in mosthorticultural characteristics however, ‘MINSYPIN3’ differs in thefollowing:

-   -   1. ‘Minsypin3’ is more erect than ‘Flogi’.    -   2. ‘Minsypin3’ has a larger flower (12 cm) than ‘Flogi’ (10 cm).    -   3. ‘Minsypin3’ has lighter pink petals color than ‘Flogi’.    -   4. ‘Minsypin3’ has small pink petaloid stamens ‘Flogi’, has        none.    -   5. ‘Minsypin3’ has got longer red feathering (0.5 to 1 cm) than        ‘Flogi’ (0.5 cm).    -   6. ‘Minsypin3’ produces more seed than ‘Flogi’.
